Human ecology is an interdisciplinary and transdisciplinary study of the relationship between humans and their natural, social, and built environments. The philosophy and study of human ecology has a diffuse history with advancements in ecology, geography, sociology, psychology, anthropology, zoology, epidemiology, public health, and home economics, among others.
The Channel Islands National Marine Sanctuary is a sanctuary off the coast of Santa Barbara and Ventura counties in Southern California 350 miles (563 km) south of San Francisco and 95 miles (153 km) north of Los Angeles. It was designated on October 2, 1980, by the National Oceanic and Atmospheric Administration and was expanded in 2007.
An ecosystem engineer is any species that creates, significantly modifies, maintains or destroys a habitat. These organisms can have a large impact on species richness and landscape-level heterogeneity of an area. As a result, ecosystem engineers are important for maintaining the health and stability of the environment they are living in. Since all organisms impact the environment they live in one way or another, it has been proposed that the term "ecosystem engineers" be used only for keystone species whose behavior very strongly affects other organisms.
Kelp forests are underwater areas with a high density of kelp, which covers a large part of the world's coastlines. Smaller areas of anchored kelp are called kelp beds. They are recognized as one of the most productive and dynamic ecosystems on Earth. Although algal kelp forest combined with coral reefs only cover 0.1% of Earth's total surface, they account for 0.9% of global primary productivity. Kelp forests occur worldwide throughout temperate and polar coastal oceans. In 2007, kelp forests were also discovered in tropical waters near Ecuador.
Regime shifts are large, abrupt, persistent changes in the structure and function of ecosystems, the climate, financial systems or other complex systems. A regime is a characteristic behaviour of a system which is maintained by mutually reinforced processes or feedbacks. Regimes are considered persistent relative to the time period over which the shift occurs. The change of regimes, or the shift, usually occurs when a smooth change in an internal process (feedback) or a single disturbance triggers a completely different system behavior. Although such non-linear changes have been widely studied in different disciplines ranging from atoms to climate dynamics, regime shifts have gained importance in ecology because they can substantially affect the flow of ecosystem services that societies rely upon, such as provision of food, clean water or climate regulation. Moreover, regime shift occurrence is expected to increase as human influence on the planet increases – the Anthropocene – including current trends on human induced climate change and biodiversity loss. When regime shifts are associated with a critical or bifurcation point, they may also be referred to as critical transitions.

An ecosystem model is an abstract, usually mathematical, representation of an ecological system, which is studied to better understand the real system.
The National Center for Ecological Analysis and Synthesis (NCEAS) is a research center at the University of California, Santa Barbara, in Santa Barbara, California. Better known by its acronym, NCEAS (pronounced “n-seas”) opened in May 1995. Funding for NCEAS is diverse and includes supporters such as the U.S. National Science Foundation, the State of California, and the University of California, Santa Barbara.
The Continuous Plankton Recorder (CPR) Survey is one of the longest running marine biological monitoring programmes in the world. Started in 1931 by Sir Alister Hardy and Sir Cyril Lucas, the Survey provides marine scientists and policy-makers with measures of plankton communities, coupled with ocean physical, biological and chemical observations, on a pan-oceanic scale. The Survey is a globally recognised leader on the impacts of environmental change on the health of our oceans.

Jackson has more than 170 scientific publications and 11 books, with nearly 40,000 citations listed on Google Scholar.
Enric Sala is a former university professor who saw himself writing the obituary of ocean life, and quit academia to become a full-time conservationist as a National Geographic Explorer-in-Residence. Sala’s present goals are to help protect critical marine ecosystems worldwide, and to develop new business models for marine conservation. He also produces documentary films and other media to raise awareness about the importance of a healthy environment, and to inspire country leaders to protect more of the natural world.
Joe Roman is a conservation biologist, marine ecologist, and author of the books Whale, Listed: Dispatches from America's Endangered Species Act, and Eat, Poop, Die: How Animals Make Our World. His conservation research includes studies of the historical population size of whales, the role of cetaceans in the nitrogen cycle, the relationship between biodiversity and disease, and the genetics of invasions. He is the founding editor of "Eat the Invaders", a website dedicated to controlling invasive species by eating them.
Carl Folke, is a trans-disciplinary environmental scientist and a member of the Royal Swedish Academy of Sciences. He is a specialist in economics, resilience, and social-ecological systems, viewing such systems as intertwined and potentially unexpected in their interactions. As a framework for resource management, this perspective brings important insights to environmental management, urban planning, and climate adaptation. He suggests ways to improve our ability to understand complex social-ecological interactions, deal with change, and build resilience, often working at smaller scales as a step towards addressing larger scales.

A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton. The second trophic level is occupied by zooplankton which feed off the phytoplankton. Higher order consumers complete the web. There has been increasing recognition in recent years that marine microorganisms.
